Building the 1500x1000mm ox build, have taken many photos throughout the buid process. Learning the process of the setting up of the machine is pretty neat. Not to mention it will definitely test your patience's when it comes to all the tedious wiring of things.

GRBL says the following for these settings.
GRBL will give up searching for a limit switch after 1.5x the max travel distance. The max travel distance is controlled by $130, (for x), $131 (for y) and $132 (for z). These numbers are also used for soft-limits, and should be set slightly below the length of your axes.

GRBL uses that for soft limits as well but it will not let homing go beyond 1.5X's of that distance. That is what I understand. If you turn on soft limits, it would stop the machine from moving farther then those distances. If you don't want to change it, move Y with in 300MM of the homing switch and it should home.

I'm good on the homing issue for now thanks. But what about the depth of the cut settings? I my 2 inch test circle is set to a quarter inch and it's cutting .0249 and now it's only cutting a hole not even a circle.

your setting for $100-103 sets your steps/mm. According to your image, you have 26.667mm/step. What tooth count is no your X and Y pulley? What microstepping are you using? I have 80 for my setup. I have 1/16 microstepping, with a 2MM pitch belt with 20 tooth pulley. Check out this site for a calculator. These will get you close then you need to dial in the dimensions after that.

Calculated that is right, but if you are not milling a 2" circle either the gcode is wrong or the steps are wrong. Move the machine in one direction only and measure. If you have a MM ruler, you can set a engraving tool in the spindle, put it on 10MM and move it 50mm it should stop on 60mm. This is how to calibrate the steps. If it is smaller, maybe it set on 16. that would be 53.33?

for Z what lead screw do you have? The way I calibrate Z is to measure a 20MM aluminum extrusion. Set Z to 0 when touching the bed, then command a 20mm(or what it measures) up in Z. then see if the extrusion fits as snug as when touching Z.
